Resumo

We evaluated the live weight (LW), morphological and testicular measures and their correlations in 31 Mediterranean buffaloes at three ages. We used seven animals at 8 months of age (T1), 13 animals at the age of 10 months (T2), and 11 animals at the age of 12 months (T3) coming from a farm of the Coastal Lowlands of Rio de Janeiro. The following morphometric measurements and testes were evaluated: rump height (RH), withers height (WH), rump length (RL), round thickness (RT), scrotal circumference (SC), testicular length (TL), testicular width (TW). Testicular volume (TV) and body mass index (BMI) were also calculated. The testicular form was determined by the ratio between the TW and TL. We found the following means for the variables LW (240.57 ± 18.36; 259.38 ± 28.66; and 331.82 ± 63.23), WH (113.28 ± 2.44; 116.23 ± 4.74; and 121.45 ± 6.95cm), RH (116.07 ± 3.09; 117.54 ± 4.97; and 125.45 ± 6.92 cm), RL (34.86 ± 2.03; 36.35 ± 2.80; and 38.09 ± 3.24 cm), RT (39.07 ± 2.22; 40 ± 2.37; and 42.91 ± 3.97cm), BMI (187.37 ± 11.45; 191.69 ± 14.61; and 222.39 ± 23.57) regarding the treatments T1, T2, and T3, respectively. We found the following means for the variables SC (17.43±1.81; 19.08±1.98; and 22.11±3.25 cm), TL (8.28 ± 0.99; 9.27 ± 1.33; and 10.68 ± 1.47 cm), TW (3.25 ± 0.25; 3.90 ± 0.58; and 4.66 ± 0.80cm), and TV (109.43 ± 24.93; 198.36 ± 87.08; and 343.83 ± 183.04 cm3 ) regarding the treatments T1, T2, and T3, respectively. The predominant form in all treatments was long. There was no difference between the T1 and T2 for the studied variables. T3 had higher averages for LW, BMI, RH, SC, TV, and TW. For the variables WH, RL, TL, and RT there was no difference between T2 and T3. There was a correlation between measurements and testicular measures WH, RH, and RL and between SC and TV, TL, and TW.(AU)

Objetivou-se com este trabalho analisar o peso vivo (PV), as medidas morfométricas e testiculares e suas correlações entre si em 31 búfalos Mediterrâneo em três idades. Foram utilizados sete animais de 8 meses (T1), treze de 10 meses (T2) e onze de 12 meses (T3), de uma propriedade da Baixada Litorânea do Rio de Janeiro. As medidas morfométricas e testiculares avaliadas foram: altura da garupa (AG), altura da cernelha (AC), comprimento da garupa (CG), espessura de coxão (ECX), circunferência escrotal (CE), comprimento testicular (CT) e largura testicular (LT). Foram calculados o volume testicular (VT) e o índice de massa corpórea (IMC), e foi determinada a forma testicular pela razão entre a LT e o CT. Foram encontradas as médias para das variáveis PV (240,57 ± 18,36; 259,38±28,66 e 331,82 ± 63,23), AC (113,28 ± 2,44; 116,23 ± 4,74 e 121,45 ± 6,95 cm), AG (116,07 ± 3,09; 117,54 ± 4,97 e 125,45 ± 6,92 cm), CG (34,86 ± 2,03; 36,35 ± 2,80 e 38,09 ± 3,24 cm), ECX (39,07 ± 2,22; 40 ± 2,37 e 42,91 ± 3,97 cm), IMC (187,37 ± 11,45; 191,69 ± 14,61 e 222,39 ± 23,57) para os tratamentos T1, T2 e T3, respectivamente. Foram encontradas médias para as variáveis CE (17,43±1,81; 19,08±1,98 e 22,11 ± 3,25 cm), CT (8,28 ± 0,99; 9,27 ± 1,33 e 10,68 ± 1,47 cm), LT (3,25 ± 0,25; 3,90 ± 0,58 e 4,66 ± 0,80 cm) e VT (109,43 ± 24,93, 198,36 ± 87,08 e 343,83 ± 183,04 cm3) para os tratamentos T1, T2 e T3, respectivamente. A forma predominante para todos os tratamentos foi o Longo. Não houve diferença entre as médias dos tratamentos 1 e 2 para nenhuma das variáveis estudadas. Para as variáveis PV, AG e IMC, CE, LT e VT o tratamento3 apresentou as maiores médias. Para as variáveis AC, CG, ECX e CT não houve diferença entre os tratamentos 2 e 3. Houve correlação entre todas as medidas testiculares e as medidas de AC, AG e CG e entre CE e VT, CT, LT.(AU)
